POWER-TRANSMISSION GEAR.

To all whom it may concern.-

Beit known that L-Josnrm H. Moanrson,

a citizen of the United States, residing at Connersville, in the county of Fayette and State of Indiana, have invented certain new and useful Improvements in Power-Trans mission Gears, of which the following is *a specification;

The object of my invention is m produce, preferably as .a' single and unitar structure, a speed-chang1ng gearing coaxia and immediately assoeiated'withaeom ensatin gearing for use in driving automo iles an other similar motor-vehicles.

The accompanying drawings illustrate my invention.-

Figure 1 is an axial section of an embodi- "ment of my invention; Fig. 2 "a transverse section on line 2 2 of Fi 1 and Fig. 3a similar section on line 3 3 0? Fig. 1.

In the drawings, and 10' indicate the two coaxial sections of the -main'drive-shait of the vehicle, being'either the rear-wheel a sleeve 14 is thedriving sprocket or gear shafts or a suitable j ack'shaft connected with the driving-wheels; Each of the shafts 10 and'il-(i'earries at its inner end a gea 11 'or 11,

respectively, which gears are the main gears of a standard compensato'r.- v

Inithp drawings I have illustrated a compensawrofa common type, consisti v of a main -body or casing 12, within whic 1 are nioixntedsevefalngairs-of idler-gears '13 andf 13, each paii' of gears 1-3 andl3 connecting .the two gears .11 and 1 1. The particular form of compensator plays no part in my present invention, and it is to he understood that any othersuitabl'e form may he used without departingtherefrom. The body 12 is provided with oppositely-extending sleeves 14 and 14, which are sleeved upon the shafts 10 and 10, respectively, ad'aeent the gears 11 and 11', respectively. Sleeved upon the 'provided with a sleeve-hub 16, which is sleeved upon sleeve 14 and carries a pinion 17-at its end. Sleeved npon sleeve 16 is an internal 'ear 18, which is arranged in aline- -ment wit pinion 17. The gear 18 is pro vided with a flange '-S.

one end a pinion 2 2, which meshes with the I internal gear 18' and the pinion l7. Sleeved iipon sleeve 14 is an internal gear 23, and meshing with said gear aresevgi'al idler-pinions 24, which are jotrnaled rpon sttids 25, carried by casing 12. Each of the v idlers 24 meshes with an adjacent pinion 26,. each carried by one of the planetary shafts adapted to be clamped by a clamp 1 Any s1 itahle means may he rsed-tocluteh the driving-wheel 15 to the compensator, and in the dram'ngs I have shown a frictioneh'tch' 27, having a member 28, which issplined upon sleeve 14 and shittable 1o trdinally thereof by a yoke 29 to conneet't is a driving-wheel 15 to the sleeve 14 or to per mit said drivingwvheel to turn loosely upon the sleeve 14. A brake 51 is arranged to actagainst themain body'ot the compensator.

The operation is as follows: Sup osing memher 28 to be shifted to the left in ig. 1, this will permit the driving-wheel 15 to ro- -tatefreely upon sleeve 14'. If said whee-l bs I .rotated so as'to rotate the pinion 17 in the- 60 -21. Gear 23 is provided with a fiangeZ-B',

direction indicated by the arrow-in Fig. 2; this will catse a rotation of gears 22 inthe. 1;

directions indicated by the arrows in Fig. 2,;

and if theinternal gears 18 and 23"he free to I rotate there will be no rotation of the easin or main body 12, and hence no rotation o shafts 10 and 10. .Thepinions 26 will'also rotate in the direction-indicatedhy'the at rows in Fig. 3, ahd'theinterlnediategears 24 will be rotated in the opposite'direction and internal gen-r 23wili be rotated freely about sleeve 14'. If the clamp he clamped upon the flange planetary movement of said gears in the di- 'l8 of gear 18,-said gear will he held sietionary, and the rotation ofgears 22 \fflll cause a} reetion'indieatedby the-arrowin Fig. 2, thus 1 driving theeonipensatqbbod 12, n a for ward direction-mab gg t 1 imil r y planetary movement of shatts 21 in' the'direc-tion indicated by them-rows in Fig. 3, thus causing a reverse rotation of the eenipensa .torsbody at a lower speed... Byshifting the member 28' to the position shom fmlng. i1

thedriving-gear 15 will be elu'tchedito sleeve amp -be'elamped I I upon the flange 23' of gear 23 there will be a g l o l intermediatespeed-re ue' 14, which, being a part of the main body of the compensator, will drit'e thecompensator forward at full speed.

I claim asmy invention 5 1. The combination with'a pair of'shaft-s, a

' pair of gears carried by the adjacent ends of i said shafts, planetary com ensating gears Jconnecting said first-mentio n edgears, a carrier for said planetary com ensatbrgears ro- .-'x' 'o tatably mounted upon said ghafts, a driving- 'gea'rconcentric with said hafts, a. sebond gear also concentric-with said shafts, a plane t ary gear carried by the compensator-carrier 3-: v i meshing with said twolastmentioned 15, rs, and means for directly connecting the r ving' gear and compensator-carrier?"

2. The combination, with apair of coaxial shafts, a compensator-easing journaledthere on, and compensator-gearing between said shafts, of a. driving-gear coaxial \withsaid' shafts, a pair of-iinternalgears coaxial with said shafts, means'for holding either ofsaid internal gears against rotation,,an d planet ary gean between the 'driving gear and each of sai internal gears.- i
